            <title>[SERVER-71167] txn_index_catalog_changes.js session garbage collection can deadlock with fsync lock in consistency checks</title>
                <link>https://jira.mongodb.org/browse/SERVER-71167</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;&lt;tt&gt;txn_index_catalog_changes.js&lt;/tt&gt; has &lt;a href=&quot;https://github.com/mongodb/mongo/blob/6f0704c3988ddfc0acff2e3438413b46cf4840e8/jstests/noPassthrough/txn_index_catalog_changes.js#L66-L71&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;a session object&lt;/a&gt; that goes out of scope before &lt;a href=&quot;https://github.com/mongodb/mongo/blob/6f0704c3988ddfc0acff2e3438413b46cf4840e8/jstests/noPassthrough/txn_index_catalog_changes.js#L79&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;consistency checks are performed&lt;/a&gt;. When performing these consistency checks, we do an &lt;a href=&quot;https://github.com/mongodb/mongo/blob/6f0704c3988ddfc0acff2e3438413b46cf4840e8/src/mongo/shell/replsettest.js#L2348-L2352&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;fsync lock&lt;/a&gt;. When the session object is garbage collected, it will try to run &lt;tt&gt;abortTransaction&lt;/tt&gt;. If this occurs while the server is fsync locked, we can get stuck because the &lt;tt&gt;abortTransaction&lt;/tt&gt; must wait for current optime to be majority committed before responding with &lt;tt&gt;NoSuchTransaction&lt;/tt&gt;.&lt;/p&gt;</description>
